  • Patent number: 5234832
    Abstract: The invention is a process for cleaning and disinfection of heat and corrosion sensitive medical instruments, particularly endoscopes in which the surfaces of the medical instruments are contacted with a detergent and disinfectant solution. The solution has a pH of from 6 to 8 and contains a low foaming nonionic surfactant, a proteolytic enzyme, a complexing agent, and an aldehyde selected from the group consisting of formaldehyde and aliphatic dialdehydes containing 2 to 8 carbon atoms and, optionally, other standard detergent and disinfectant constituents. The cleaning solution is heated to 55.degree. to 65.degree. C. and kept at that temperature for 1 to 15 minutes during contact with the surfaces of a medical instrument. The surfaces are rinsed at least twice with water, the water being heated to 55.degree. to 65.degree. C. at least in the last rinse cycle and the medical instruments are dried with sterilized hot air at a temperature of 40.degree. to 60.degree. C. Water having a hardness of 3.degree.
